pw300

Program Overview

The PW300 family, developed by Pratt & Whitney Canada, was created to support a wide range of business jets and selected regional aircraft applications. Since 1985, MTU Aero Engines has worked with Pratt & Whitney Canada on this engine family, establishing a long-standing industrial partnership in the business aviation segment.

The PW300 engines are two-spool turbofans designed to deliver efficiency, reliability, and low operating costs for midsize and large business aircraft. The family includes variants such as the PW305, PW306, and PW307, each adapted to different thrust levels and aircraft platforms.

Over more than three decades of service, the PW300 has built a reputation for technical robustness and application flexibility. Its use on aircraft such as the Dassault Falcon 7X, Falcon 8X, Gulfstream G200, Learjet 60, and Cessna Citation Latitude shows the broad reach of this engine family in the business aviation market.

Propulsion System Architecture

Thermodynamic Configuration

The PW300 is a two-spool turbofan engine positioned in the approximate 4,700 to 7,000 lbf thrust range, depending on the version. This category allows the engine to power light, midsize, and large business jets, as well as selected regional aircraft.

As a turbofan, the PW300 uses a front fan to move air through the engine. Part of this airflow enters the core, where it goes through compression, combustion, and expansion through the turbines. The remaining airflow moves through the bypass duct, helping generate thrust more efficiently and quietly.

In simple terms: the PW300 is a turbofan engine family designed mainly for business jets, combining reliability, efficiency, easier maintenance, and a flexible architecture for different aircraft platforms.
